What started as just a shot on the one lone hunter has very slowly zoomed out to reveal the surrounding art behind it. Accompanied by the sounds of a crackling fire, ambient music, a stern-voiced man and a frightened-sounding woman, five hours later, it looks like this:

There's very little information beyond this to ascertain just what Ubisoft is teasing and when they will tell us already. Many outlets are speculating some sort of prehistoric Assassin's Creed.
